Microsoft, however, has to distribute code for any change to the hundreds of millions of PCs where its desktop software resides. It thus releases new products infrequently.

The document de- scribes the so-called OpenCV 2.x API, which is essentially a C++ API, as opposite to the C-based OpenCV 1.x API. The latter is described in opencv1x.pdf. OpenCV (Open Source Computer Vision Library) is an open source computer vision and machine learning software library. OpenCV was built to provide a common infrastructure for computer vision applications and to accelerate the use of machine perception in the commercial products. Being a BSD-licensed product, OpenCV makes it easy for businesses to utilize and modify the code. The library has more than 2500 optimized algorithms, which includes a comprehensive set of both classic and state-of-the-art computer vision and machine learning algorithms. These algori- thms can be used to detect and recognize faces, identify objects, classify human actions in videos, track camera movements, track moving objects, extract 3D models of objects, produce 3D point clouds from stereo cameras, stitch images together to produce a high resolution image of an entire 1 scene, find similar images from an image database, remove red eyes from images taken using flash, follow eye movements, recognize scenery and establish markers to overlay it with augmented reali- ty, etc.

Chapter 1 Introduction From a developer’s perspective, the APIs for desktop PCs and enterprise systems have been a daunting combination of complexity and confusion. Over the last 10 years, Java™ technology has helped simplify and tame this world for the benefit of everyone. Developers have benefited by seeing their skills become applicable to more systems. Users have benefited from consistent interfaces across different platforms. And systems vendors have benefited by reducing and focusing their R&D investments while attracting more developers. For desktop and enterprise systems, “Write Once, Run Anywhere”™ has been a success. But if the complexities of the desktop and enterprise world seem, well, complex, then the connected device world is even scarier.

  • Achieving High and Consistent Rendering Performance of Java AWT/Swing on Multiple Platforms
    SOFTWARE—PRACTICE AND EXPERIENCE Softw. Pract. Exper. 2009; 39:701–736 Published online in Wiley InterScience (www.interscience.wiley.com). DOI: 10.1002/spe.920 Achieving high and consistent rendering performance of Java AWT/Swing on multiple platforms Yi-Hsien Wang and I-Chen Wu∗,† Department of Computer Science, National Chiao Tung University, Hsinchu, Taiwan SUMMARY Wang et al. (Softw. Pract. Exper. 2007; 37(7):727–745) observed a phenomenon of performance incon- sistency in the graphics of Java Abstract Window Toolkit (AWT)/Swing among different Java runtime environments (JREs) on Windows XP. This phenomenon makes it difficult to predict the performance of Java game applications. Therefore, they proposed a portable AWT/Swing architecture, called CYC Window Toolkit (CWT), to provide programmers with high and consistent rendering performance for Java game development among different JREs. They implemented a DirectX version to demonstrate the feasibility of the architecture. This paper extends the above research to other environments in two aspects. First, we evaluate the rendering performance of the original Java AWT with different combi- nations of JREs, image application programming interfaces, system properties and operating systems (OSs), including Windows XP, Windows Vista, Fedora and Mac OS X. The evaluation results indicate that the performance inconsistency of Java AWT also exists among the four OSs, even if the same hardware configuration is used. Second, we design an OpenGL version of CWT, named CWT-GL, to take advantage of modern 3D graphics cards, and compare the rendering performance of CWT with Java AWT/Swing. The results show that CWT-GL achieves more consistent and higher rendering performance in JREs 1.4 to 1.6 on the four OSs.

    Introduction to Computation and Problem Solving Class 17: Lab: The Graphics 2D API Prof. Steven R. Lerman and Dr. V. Judson Harward 1 The Origins of the Java Graphics 2D API • The original Java GUI toolkit, the AWT, was a quick and dirty solution. It used native peer components to draw all widgets. • Swing draws all components except the top level containers using Java methods rather than relying on platform specific widgets. • To do this, Swing required improved graphics. • The Java 2D API was born as enabling technology for Swing. • There is now a Java 3D API also. • See tutorial at http://java.sun.com/docs/books/tutorial/2d/index.html 2 1 Java Graphics Architecture Swing Java AWT Java 2D Graphics API Platform Windowing System Platform Graphics Architecture 3 NgonApp Custom Drawi ng Swing Components: JLabel and JTextField 4 2 So, How Do I Draw in Java • You might think that if you want to do your own drawing in Java, you do it in the main thread just as you create a GUI out of components in the main thread. • In fact, you have to create components on which you draw like all your other GUI components in the main thread. • But the drawing has to be done in the event thread. • And to understand why, we need to start by considering when drawing happens. 5 When Does a GUI Get Drawn? • On initial display (but not necessarily when the program gets started) • When the display gets “damaged”. For example when it gets hidden and then re-exposed.
